Hot and Cold Breathing-Air Temperature Control

The Bullard HC2400 is designed to provide temperature adjustment for breathing air delivered to a compatible supplied-air respirator.

Using compressed air and a vortex-based temperature-control process, the assembly can provide temperature-conditioned airflow without requiring an electrical connection at the tube.

This makes it useful in environments where operators may benefit from warmer or cooler supplied air.

Important: Temperature-control performance depends on the incoming air temperature, pressure, airflow, and operating conditions.

The HC2400 does not filter, purify, or remove contaminants from the breathing-air supply.

Designed for Demanding Industrial Applications

Operators wearing supplied-air blasting helmets and protective equipment can experience uncomfortable temperatures during extended work periods.

The Bullard HC2400 helps address operator comfort in applications such as:

• Industrial abrasive blasting

• Structural steel surface preparation

• Shipyard and marine maintenance

• Bridge restoration

• Tank and vessel blasting

• Industrial spray painting

• Commercial sandblasting operations

• Industrial coating and surface preparation

1/4" Industrial Interchange Quick-Disconnect

The HC2400 features a 1/4" industrial interchange quick-disconnect nipple for connection to compatible compressed breathing-air supply equipment.

Before ordering, verify:

• Original Bullard air-control model

• Required quick-disconnect fitting profile

• Compatible breathing-air supply hose

• Respirator model and approved configuration

• Required operating pressure and airflow

• Available compressed-air capacity

Temperature-control assemblies may require more compressed air than standard constant-flow devices. Verify that the air supply meets Bullard's requirements for the HC2400 and the complete respirator system.

Compatible Equipment

Designed for approved Bullard supplied-air respirator configurations.

Potential applications include:

• Bullard 88VX Series Abrasive Blasting Respirators

• Compatible Bullard Type CE Supplied-Air Blasting Helmets

• Other Bullard supplied-air respirators specifically approved for use with the HC2400

Compatibility must be confirmed against Bullard's respirator and air-control instructions.

The HC2400 should not be substituted for an F30, F35, or other air-control assembly unless Bullard approves that configuration.

Common Reasons for Replacement

• Existing temperature-control tube is damaged

• Temperature adjustment no longer functions properly

• Quick-disconnect nipple is worn or damaged

• Air leakage at the assembly

• Existing air-control tube is missing

• Replacing worn equipment during respirator maintenance

• Installing a manufacturer-approved temperature-control configuration

Important Breathing-Air Safety Information

The Bullard HC2400 is a breathing-air temperature-control component, not an air purifier or carbon monoxide removal device.

The compressed breathing-air source must meet applicable respiratory protection requirements, including OSHA 29 CFR 1910.134.

Use only manufacturer-approved breathing-air hoses, fittings, and components in the respirator configuration specified by Bullard.

Follow Bullard's instructions for operating pressure, airflow, total hose length, and approved component combinations.

Never substitute ordinary shop-air hoses or unapproved pneumatic fittings for breathing-air equipment.
